Well now that ive spent a million bucks on my short block which isnt even assembled yet ive turned to the used market for a couple items. I found a guy selling a 750 Double Pumper Holley, he said It would probably need a new bowl/ float. Which I could get dirt cheap new. $40 for the carb though. Would it be a gamble? Or easier to just get a new one.

You know I really want to stay Edelbrock when it comes to my carb but I want to run a double pumper, im pretty sure they dont make one, hopfully im wrong...

edelbrock all models are vaccum operated secondaries and id stay away from the 40 dollar deal that sounds like a mess unless your really good with holleys working at togs you should be able to get a good deal on a classic holley model they about 319 new at your discount why fool with some ones used mystery junk. just my opinion

Yeah that was my main stab is to buy it from work. But I just saw a Holley rebuild kit and then I saw this... I dont think its worth the hassel. Good call, I agree.

Holleys are great and easy to rebuild. Seeing all your other post though I don't think you need to run a double pumper. You would do better with a 750 Vacuum Secondary. Look for a 3310-1 or if you have the funds one of the 770 Street Avengers. You could also get one of the other 3310's and convert it to a metering block like the 3310-1, thats what I'm doing.

For $40,I'd buy it.
For the the price of a new float bowl and a rebuild kit,you'd make out decent.
Its a $300 carb new I believe.
or,you could just wait for a 3310 vacuum secondary.

Check the throttle shafts for play, when the holleys get old the throttle shafts wear. If the shafts are really loose don't buy it. And check the baseplate for any cracks. Rebuilding the Holley is easy and cheap, just find a friend willing to let you test and tune it on his car to verify it's in working order before firing up your new motor with it. Ebay has oodles of Holleys for sale, I seem to keep collecting them at sometimes less than $20 each. Bob

aw heck,,,just spring for the HP950 to go with the serpentine belts...while you're spending money :D

From reading your other posts and questions, 2 things I would not recommend to you A - don't assemble your own shortblock, B - don't attempt to validate a used carburator. Please leave these 2 jobs to professionals. Nothing worse than trying to start up a new motor with a ratty carb, only to wind up dumping huge volumes of raw fuel into brand new cylinders, not to mention the eternal cranking and the probablility of wipng a new cam.

Sorry - some things just aren't worth trying to cut corners. If you are strapped for cash, I would either hold off on completion or make a valid attempt to liquidate whatever I could get my hands on to drum up the funds.

Phil,you should be buying the valve spring/retainer kit I mentioned ;) :D

Phil;

You got the short block back from Don?
Right now, you REALLY want to invest your $$$ on what you have sitting in front of you. The carb and the serp belt and the other peripherals need to wait.

Get the heads done, get the motor assembly finished...

Santa may bring you something, who knows?
In any case, don't spend your money on racing gas and track fees before the motor is built. Spend it one step at a time and get each stage COMPLETED before you move on to the next.

You've got a good base started, but it's way too easy to spend lots of money and buy all the pretty chrome and aluminum and worry about painting colors. Take your time and do it right!

Hey Curt, I got my engine from a guy in Half Moon Bay and took it to Don, he did the boring and magna, I someone else do the cam bearings because i got all the way across town and forgot, so I just dropped it off at Dels Machine on El Camino (right by work) Don is balancing my rotating assembly this week, he didnt want to put it together because of the guarantee on parts. It would probably be alot easier and quicker to have someone put it together everyone is making it sound like its a pretty heafty journey.
Im just making my parts list and trying to get my combo right, im not buying any of this stuff yet.... shortblock first smile.gif

Heres the guy i bought my 800 dp off of and couldn't be happier. His names kirk out of San Angelo,TX

I donno, keep it clean, rotate the rings right, torque it down in steps while rotating the crank and beating on it's ends ta set the thrust bearing.. Install the piston/rod assemblies using a good ring compressor and a heavy wooden handled hammer while you listen to that "THUD"... Torque the rods down in steps...

Roll her over and mount the heads and torque down in steps again?????? Set the rockers and lifters however.....

What's the problem with him doing it himself??

AND don't get started on me leaving some of the nit-picking things out like gaubbing the shim headgaskets and putting the oil pump driveshaft and fuel pump rod in...

Heck, a copy of HP Books, "How to Rebuild a BB Chevy" will take care of all that stuff IF he can read........

I guess I'm too "shade-tree" here??? I gotta do it myself for my own "grin" factor once she lights off!!!

Thanks PD smile.gif Thats what I like to hear...

PDQ;

You'll notice I never said don't do the assembly...

I too read the shade tree mechanic manual and have done a lot, one page at a time. Now in fairness, I never built a 1000HP aluminum rocket sled that requires tight tolerances and incredible patience, but I didn't think assembling a fairly basic 454 was all THAT difficult.

Time consuming, OH H*** YES, but not difficult...

A good book, good pictures and good descriptions... works miracles!

I think a Holley float bowl is about $40, then you'd need to rebuild it. frankly, I think you'd be better off running a 3310. Double pumpers are pig rich to start with and don't respond all that well to being leaned out. The 3310 is much better suited to the street. I also think it would be better for you to pop for a new one rather buying some unknown quantity used one. It's not easy to find a used Holley that somebody hasn't butchered up, that why they're selling it. smile.gif

Tom

Which one is the 3310?

You know I guess I'll decide this Friday or Monday when my balanced assembly gets back... eh
